No buttons being held during the process. Fortunately, I was able to Target disk mode to both internal drives and backup. What would cause this after years of perfect use and nothing different happening? This may have been caused by a corruption in the Operating System OS. I would recommend doing a fresh install of the OS. If you have any further issues with it, please feel free to contact our technical support team.

One of my helpers offered to finish formatting the new SSD. By accident he did. Any suggestions? A Fusion drive will show up as a single volume. When looking in Disk Utility you will only be able to see the single volume and the name that was provided to it. You will then be able to see every SATA drive in your computer independently. If you are still not able to find the SSD or confirm the Fusion was set up correctly, please feel free to contact our Technical support team!

My goal is to have the original This is very much possible. Once you install the new SSD, you will want to boot your computer as you normally would. You will then be able to go into disk utility and format the new SSD. Once the new SSD has been formatted you will be able to proceed with the fresh install of Once both drives have operating systems on them, you will be able to choose what drive you would like to boot up off of and use.

Please take a look at this Apple document for instructions on how to use and set this up. Hi, I currently have a Mac Mini Late 2. It is running Yosemite perfectly, it is not in a fusion array. I have just purchased another Mac Mini server late , this time a 2. So the question I have are 1. Is this just a straight for swap out from the 2. You will want to break the fusion drive on the 2. You can then swap in the new SSD you want. Since both drives will be formatted and ready for use you will not run into an issue. It is only when you go into disk utility in the built-in recovery partition that it will try and force a fusion drive on you.

Best practice of course is to be sure everything is backed up before beginning just in case things do not go according to plan. Many thanks for the speedy response! If somewhere down the track could I look to setup a Fusion array with the new configuration? I am of the understanding that it will wipe all my data on both drives. Is this something I can do which will work fine without issues or would you advise against setting up a fusion drive with SSD components that are not factor?

The easiest way would be doing what we advise against in this article. Boot your computer into the built-in recovery partition and proceed to Disk Utility to format your drives. It will automatically erase the information on both drives and create a fusion drive for you at that point. Hi, First thank you for that description, I got a new Mac mini with all three In your article mentioned factores. It helped me. Only updated Yosemite.

How can I make a clean installation of Yosemite on my SSD, without using the recovery disk-utility-management? Backup is not required, cause no important data on Mac. The opposite of a updated installation. Finally I made it! Only with those two conditions it will work without problems. I have a Macmini6,2 with Mavericks I just received my Data Doubler kit from you today, and read about this potential issue with the Fusion drive array setup.

The goal is to make my SSD the main system disk and to use the original factory hard disk my secondary drive for data. I go in depth in how I did it myself here. The most important thing to remember is if you ever go to format the original HDD or new SSD while both are in your computer, it will try and create a fusion drive. After installing the OWC data doubler using a Samsung evo gig to the lower tray and rebooting, the Mac will not boot into the existing The drive showed up in the Disk Utility that was available from the automatically started repair screen with a green icon as an external drive.

The new gig was clearly available. I formatted the gig using the Mavericks DU and have started the recommended Internet Restore command-R now after auto reboot I get the blinking question mark screen…. After reconnecting and booting up it launched directly into my existing Am I correct in thinking that this is only an issue with certain versions of disk utility pre installed on the recovery partition?

I do not think I will have any problem installing the 2nd drive but my concern is transferring the system to the new drive. Does cloud already have this backed up or do I need to back it up to another drive? I guess once I get the 2nd drive installed then I will install the system on it? Do I keep or use my new drive for the system only? I already have a tool kit and the extra internal drive cable I guess it came in the bundle?

If you prefer keeping your two drives separate you have two options for keeping your data and OS file separate. My preferred method was outlined in this blog and another method is outlined in our video here. Both successfully see the HDD when connected externally now. My fear is when I finally connect it internally that the bootcamp setup will be lost and it will try to create a Fusion Drive.

If you are not going to be reformatting either of the drives you have no risk of losing any partitions. The fusion drive is only forcefully created when formatting one of the two internal drives. Better to swap lower with upper drives? It is possible this is perfectly normal; it all depends on what USB device you are using to install the operating system. If it is USB 2. If you have the option of a USB 3. If you are already using a USB 3. How can I restore to factory settings? I did upgrade to SSD and followed the above steps in when I got my mac mini. But how do I restore it to factory settings.

Any help would be great. This can be an external clone backup or a recovery partition on a time machine backup. Once you have erased your SSD from an external you may reinstall the OS from the built in recovery partition. Great tips,.. I intended to create a fusion drive, have read several articles, and have have notes on how to name each drive and create the fusion drive in detail. However, if mavericks will create a fusion drive automatically by booting to the newly installed SSD and HD, what is the benefit of going into all of that detail?

That is an excellent question Jonathan. Thanks for the great tips Chris. I tried to wing it and on the fourth try I found this page and your directions worked great. My plan was to buy an external drive to run the system and backup before the mini goes back home to mostly be gutted and refilled under warranty and then install the SSD after return.

I installed a fresh version of the OS 3. That was nice. The problem is that as I take personal junk off the old hard drive, they disappear from the usb connected SSD also. Got any suggestions to unlink these drives or what is going on?

Special Note for Adding an SSD to a Mac mini.

Would it be advisable to follow the instructions in the special note for adding a SSD to a mac mini to be safe? I will back up all data to a external hard drive before commencing. You will definitely want to follow the above steps if you do not wish to end up with a Fusion drive. I originally followed the install notes above, to avoid accidental fusion drive creation. As far as I know, the update does not use the recovery partition boot for anything. Beyond that, is there any way to update the recovery partition on my disks to resolve this issue?

As with any update we do recommend backing up your drive s before doing any upgrades or updates. Downloading and updating your Mac Mini current Operating System drive to Mavericks will not force your drives to become Fusion. I bought your kit to have 2 SSDs. Hi — how can I tell whether or not my Mac Mini shipped with I bought it from Best Buy in September but for all I know it could have been sitting in stock for the past year.

Am I understanding correctly that if I can verify that it did not ship with The safest thing to do is assume it came with Drive Genius is a great piece of software that will allow you to format drives. It has a few other features that come in handy for Hard Drives as well. It does have a defrag feature that should never be use on SSD or Fusion drives.

If the Disk Utility is not usable, what method can I use? Going to proceed as follows have current hard drive formatted with partitions: 1. OS drive GB operating system, 2. Music GB itunes and all music related files 3. Data GB all data related 4. I clone for major backups and use Time Machine too. Do you see a problem in this procedure? Looking to get fastest SSD speed for Blackmagic to operate at highest video settings. The partitioning layout sounds good. We do not recommend restoring from clones, we only recommend clean installs and using migration assistant to copy information.

I learned from you guys what Apple could not tell me in over 2 hours on the phone with support. Bungled my install and learned how to get the SSD identified again by comments in this blog. I have a Mac mini 2. I used Time machine to move stuff over from my previous computer. I installed the ssd and kept the factory hd. Followed all the directions and updated the software.

The Samsung Trim corruption problem was indeed specific to linux, caused by a kernel bug. Quote: Does anybody know if data corruption from TRIM is actually real or just a vestigial concern stemming from that Linux problem? There was a vestigial Mac concern way back too, I think from OWC tests on their Sandforce based drives at the time they recommended against it. Today, SSDs some, most, nearly all? I don't think it's needed in the latest version of OSX correct?

If it is off you can turn it on if you want to from the command line with 'sudo trimforce enable'. It's not really possible for the drive itself to handle the same cleanup that TRIM handles because that cleanup requires knowledge at the file system level about which logical blocks are still used vs not used.

Various drives may have features that counter some of the "traditional" performance degradation you'll see without TRIM, making it possible to conclude you don't absolutely need TRIM support. But the drives aren't taking over the benefits that come from TRIM. B04 SMC Version system : 1.

Not that it would make a difference. The system is definitely faster, but I'm wondering if I can eek any more out of it to get closer to max SATA 2 speeds. Replacing "enable" with "disable" will turn it off. Moderator et Subscriptor. Voix des Airs. Ars Tribunus Militum et Subscriptor. Voix des Airs wrote:. Scud wrote:.
